Restricted area of the Courpière flood PPR (63DDT20070010) approved 07-12-2010 — Puy-de-Dôme
Description
For natural PPRs, the environmental code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures may be foreseen to avoid exacerbating the risk.
Depending on the hazard level, each area is subject to an enforceable settlement. Regulations generally distinguish three types of zones:
1- “Building Prohibition Zones”, so-called “Red Zones”, when the hazard level is strong and the general rule is the construction ban;
2- “prescription zones”, known as “blue zones”, where the hazard level is average and projects are subject to requirements adapted to the type of issue;
3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial activities could exacerbate risks or cause new ones subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code).
The Courpière flooding PPR has 8 zones:
no-Building Zones
— R1: area of expansion of unurbanised floods in low contingencies
— R2: area of expansion of unurbanised floods in medium contingencies
— R3: High hazard zone other than urban areas and urban centre
— R3u: High hazard zone in urban areas and urban centre
areas subject to requirements
— O1: Low hazard zone outside the unurbanised flood expansion zone
— O2i: industrial zone in medium contingencies
— O2u: urban centre in medium hazard zone
— O2: other urbanised areas in medium hazard zones
